[en] The published data on the synthesis, structures and properties of triorganyltelluronium salts are generalised and systematised. Special attention is given to the applications of these compounds in preparative organic synthesis.
[en] Data on the synthesis, reactions and structures of monoorganyl derivatives of tellurium(IV) (σ-telluranes) RTeX3 are systematised and generalised. The use of these compounds in preparative organic chemistry is considered. The bibliography includes 238 references.
[en] An extended cross beam method with optical signal detection was used to study inelastic collisions of mono-energetic electrons with molecular tellurium at energies up to 200 eV. It was found that both dissociative excitation of the Te2 molecule to atomic tellurium, and direct excitation of Σ-Σ band system of the Te2 molecule occur. 7 refs., 2 figs., 2 tabs
[en] Enthalpy increment measurements on La2Te3O9(s) and La2Te4O11(s) were carried out using a Calvet micro-calorimeter. The enthalpy values were analyzed using the non-linear curve fitting method. The dependence of enthalpy increments with temperature was given as: Ho(T) - Ho(298.15 K) (J mol-1) = 360.70T + 0.00409T 2 + 133.568 x 105/T - 149 923 (373 ≤ T (K) ≤ 936) for La2Te3O9 and Ho(T) - Ho(298.15 K) (J mol-1) = 331.927T + 0.0549T 2 + 29.3623 x 105/T - 114 587 (373 ≤ T (K) ≤ 936) for La2Te4O11
